LISTING-PLOW.

Specification of Letters Patent.

Patented Mar. 14:, 1916.

Application filed October 2, 1914. Serial No. 864,672.

To all whom it may concern Be it known that I, THOMAS FERGUSON, a citizen of the United States, residing at Tiptonville, in the county of Lake and State of Tennessee, have invented new and useful Improvements in Listing-Flows, of which the following is a specification.

This invention relates to listing plows, and it has for its object to produce a device of this class which is simple in construction and effective in operation.

A further object of the invention is to simplify and improve the construction of the plow units utilized in the make up of the improved lister.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawing,Figure 1 is a top plan view of a listing plow constructed in accordance with the invention. Fig. 2 is a side elevation of the same. Fig. 3 is a rear view. Fig. 4 is a transverse sectional detail view taken on the line 33 in Fig. 2.

Corresponding parts in the several figures are denoted by like characters of reference.

The improved listing plow is composed of two plow units A and B, the former being a right hand plow and the latter a left hand plow. Said units are mounted on the standards 15 of beams 16, said beams being provided at their forward ends with offsets 17 extending toward each other and having forwardly extending brackets 18 which are rigidly connected together by means of bolts or rivets 19, the latter serving also for the attachment of the clevis plates 20. The beams are connected together at their rearward ends by a screw threaded rod 21 having nuts 22 and a sleeve or spacing member 23, the latter being of proper dimensions to maintain the plow units at the desired dis tance apart. The ends of the rod 21 also serve to support the forward ends of the handles 24, the latter being connected to gether and spaced apart by the rung 25. which latter is supported on braces 26 connected with the standards. Each plow unit includes a landside 27 having on its inner face a wear plate 28 and provided in its outer face with a recess 29 wherein the standard 15 is seated. The landside member is also provided with a frog 30 on which the share 31 and mold board 32 are secured. Reinforcing blocks 83 which are seated on the top edges of the landside members have their forward ends abutting on the mold boards which are thereby reinforced; said blocks also serve to reinforce the standards for the passage of the bolts 34; whereby the handle braces are connected with said standards.

It will be seen from the foregoing description taken in connection with the drawing hereto annexed that I have produced a lister of simple, durable, light and inexpensive construction, the plow units of which are properly spaced apart, the distance between said units being governed by the length of the spacing sleeve 23.

Having thus described the invention, what is claimed as new, is

l. A plow unit consisting of a landside member having a recess in its outer face and provided with a laterally extending frog, a wear plate mounted on the inner face of the landside member, and a share and mold board mounted on the frog.

2. The combination with a beam having a downturned standard, of a plow unit comprising a landside plate having a recess for the reception of the standard, and a laterally extending frog, a share and a mold board mounted on the frog, a block supportedon the top face of the landside member, and a bolt extending through said block and through the standard, the forward end of said block abutting on the portion of the mold board that extends above the landside member.

In testimony whereof I affix my signature in presence of two witnesses.

THOMAS FERGUSON. Witnesses B. F. LEDUKn, J. P. ALEXANDER.
